Part Number:SA555
Hello Sir
I am trying to use the pulse-width modulation function of SA555 as an A/D converter.
In the application, I hope SA555 outputs a PWM signal with its duty cycle varying linearly with the voltage amplitude of the external analog signal applied to pin 5 (CONT).
However I got a PWM waveform with variable duty cycle together with variable frequency, and the duty can only vary from 50% to 100% (VCC= 5V or 12V).
I did not apply a continuous pulse train as clock to pin 2. Is it possible to accomplish the function without using a continuous pulse train ?
Best regards

Hello everyone, some questions I want to ask.
Sorry, my English is not good, I can only translate from the Internet, please forgive me.
The operational steps are in accordance with the official manual dlpu019a.pdf
First question: Calibration board size of the square problem.
- On page 32 of dlpu019a.pdf "For example, if each square is 2 cm wide, enter "2" into the prompt"
Since the size of the square of the example is "2 cm", you can enter "2" in the command window.
However, I measure my square size is "0.9 cm", so I don't know if I can type "0.9" directly into the command window. Thank you.
Second question: Because of the red line in the picture , If I want the point cloud distance unit to be changed, where should I go to change the size
For example: cm changed to mm, where can I go to set it?

Hi!
I have to minimize the time of boot of .
So, I have remove the sevices, by "systemctl disable [service]" and by remove the links from rcX.d.
Result: the boot time has no changed.
Am I have to setup the uboot? By changing the dts-files?
Dear Sir,
I converted the Tensorflow model to onnx model, now i want to import the same converted model through TIDL Import tool to generate .bin files.
I have gone through TIDL Deep Learning user guide, but I couldn't find any reference for this process other then Tensorflow and Caffe models.
Kindly help me in this.

Hi,
this is the follow up question to the problem mentioned in the link below
we were able to address the problem by doing the code download from the ARM(linux) because it was very consistently taking around 4 sec for doing the same download but the DSP still has to communicate with the same slave device using I2C read,write which can't be done from ARM. This was achieved by the ARM side first doing the code download and sending a message to the DSP notifying the same. Upon receiving the this message, we pinmux the I2C bus from the DSP(given below) and carryout some periodic I2C transactions by pinmuxing the bus opening the bus performing read/write and closing the bus on each transaction. (Note: The ARM doesn't do any transactions after this to avoid conflict over the bus)
(PINMUX from DSP)
regVal = 0x60002;
((CSL_padRegsOvly)CSL_MPU_CORE_PAD_IO_REGISTERS_REGS)->PAD_GPIO6_10 = regVal;
regVal = 0x60002;
((CSL_padRegsOvly)CSL_MPU_CORE_PAD_IO_REGISTERS_REGS)->PAD_GPIO6_11 = regVal;
CSL_l4per_cm_core_componentRegs *l4PerCmReg =
(CSL_l4per_cm_core_componentRegs *) CSL_MPU_L4PER_CM_CORE_REGS;
CSL_FINST(l4PerCmReg->CM_L4PER_I2C3_CLKCTRL_REG,
L4PER_CM_CORE_COMPONENT_CM_L4PER_I2C3_CLKCTRL_REG_MODULEMODE, ENABLE);
while(CSL_L4PER_CM_CORE_COMPONENT_CM_L4PER_I2C3_CLKCTRL_REG_IDLEST_FUNC !=
CSL_FEXT(l4PerCmReg->CM_L4PER_I2C3_CLKCTRL_REG,
L4PER_CM_CORE_COMPONENT_CM_L4PER_I2C3_CLKCTRL_REG_IDLEST));
It is observed that the I2C read and writes are not consistent. We saw that 10 out of 100 write resulted in it failing almost 10-20 times with I2C_STS_ERR_TIMEOUT and the read are even worse with almost 10-30 read fails with I2C_STS_ERR_TIMEOUT.
We then tried to debug it by doing the some read transactions and capturing it using a logic analyzer to see what was going wrong and following was observed,
we noticed a peculiar observation from the captures, was that there is no clock stretching just after the address read block from ARM but it does stretch every time from DSP.
Conclusion
ideally the code download and read/write transactions should happen in the DSP but as mentioned in the link above we are not able to do it because the timing is inconsistent taken to download from DSP and hence download was moved to ARM and read write transactions done from DSP because it required do so.
I2c driver configurations from DSP ad follows,
bus_no = 2;
i2c_cfg.enableIntr = true;
I2C_socGetInitCfg(bus_no, &i2c_cfg);
I2C_socSetInitCfg(bus_no, &i2c_cfg);
/*
* AM5 DSP does not have a default Xbar connection for I2C
* interrupt, need the following Xbar interrupt configuration
*/
/* Use reserved DSP1_IRQ_86 for I2C bus 5 */
CSL_xbarDspIrqConfigure(DSP_INSTANCE, CSL_XBAR_INST_DSP1_IRQ_86, CSL_XBAR_I2C5_IRQ);
/* Use reserved DSP1_IRQ_87 for I2C bus 3 */
CSL_xbarDspIrqConfigure(DSP_INSTANCE, CSL_XBAR_INST_DSP1_IRQ_87, CSL_XBAR_I2C3_IRQ);
I2C_init();
I2C_Params_init(&i2cParams);
i2cParams.bitRate = I2C_400kHz;
i2c_bus_handle_st[bus_no].i2c_handle = I2C_open(bus_no, &i2cParams);
we are using ti provided I2C_Transfer to read/write from DSP and ioctl for I2C transfer from ARM.

Hi Can you give me a soluction for AC to DC (85-264Vac input, 30V/6A, with PFC) about 200 watts?
Part Number:PTH08T240W
I want an LM3880 power sequencer to control PTH08T240Ws connecting FLAG pins to inhibit pins directly. Referring to the datasheet of LM3880, FLAG pins are limited to MAX. 6.0V. But I cannot find what voltage is loaded to the Inhibit control pin of PTH08t240w. I use VI 12V for pth08t240w. Are Inhibit pins lower than 6.0 V even when pth08t240w is enable ?

Hi everybody ,
In this page : https://e2e.ti.com/support/processors/f/791/t/689876 is mentioned that by updating the "tidl_tfImport.cpp" and re-building the import tool in the release package we can modify or add layers. We tried to rebuild the import tool as described in the TIDeepLearningLibrary_UserGuide.pdf (section 3.6.1).
I get errore both on command and on bash(Please visit the site to view this file) ( see screenshot attached ) .How can I proceed ?

Part Number:TLV320AIC3204
Hello,
I am using TMS320C5515 and codec AIC3204 for audio project.
Inside DSP C5515 i am generating 15 bit sine wave and then setting different codec gains (DAC and HP).
Without load when i use negative gains of DAC below -6 i am getting highly distorted signal at codec output.
Below is my experimental results captured on Tektronik Digital Oscilloscope
The codec is set to run at 1.8V.
| DAC Gain | HP Gain | Voltage P2P | RMS | Waveform Description |
| 0 | 0 | 860mV | 250mV | Sinewave |
| -1 | 0 | 780mV | 223mV | Sinewave |
| -2 | 0 | 700mV | 199mV | Sinewave |
| -3 | 0 | 640mV | 179mV | Sinewave |
| -4 | 0 | 580mV | 160mV | Sinewave |
| -5 | 0 | 540mV | 142mV | Sinewave |
| -6 | 0 | 500mV | 128mV | Sinewave |
| -7 | 0 | 480mV | 115mV | Sinewave |
| -8 | 0 | 440mv | 104mV | Sinewave |
| -9 | 0 | 400mV | 93.2mV | Distorted Sinewave |
| -10 | 0 | 384mV | 83.4mV | Distorted Sinewave |
| -11 | 0 | 368mV | 75.5mV | Distorted Sinewave |
| -12 | 0 | 336mV | 67.5mV | Distorted Sinewave |
Query: How can i achieve a clean sinewave of 100mv with THD < 1%. Can the currently selected codec AIC3204 and DSP 5515 satisfy the requirement. If yes what is the specific codec settings i must use to achieve it. The data sheet of codec mentions DAC gain range of -63 to 24. But i get highly distorted waveform at -6db itself.
Please help me resolve this issue.
Thanks,
Swamy

Hello,
I have confusion between Temperature resolution settings & Temperature register acquisition size.
Below is the description below "7.6.2 Address 0x01 Temperature MSB"
"
The temperature register is a 16-bit result register in binary format (the 2 LSBs D1 and D0 are always 0). The
result of the acquisition is always a 14-bit value, while the resolution is related to one selected in Measurement
Configuration register. The temperature must be read LSB first."
Understanding 1:
Temperature resolution with ’01:11 bit’ is with respect to sampling rate. So ’00:14 bit’ mean 14-bit sampling and ’01:11 bit’ mean 11-bit sampling of temperature value. Whatever the resolution, still all 16-bits (TEMP[15:8], TEMP[7-0]) will represent the Temperature value in digital format.
Understanding 2:
If Temperature resolution is ’00:14 bit’, do I need to consider only 16 bits (D15-D2 and D1 D0 are always 0). (TEMP[15:8], TEMP[7-0])
If Temperature resolution is ’01:11 bit’, do I need to consider only 13 bits (D12-D2 and D1 D0 are always 0). (TEMP[12:8], TEMP[7-0])
If Temperature resolution is ’10:8 bit’, do I need to consider only 10 bits (D9-D2 and D1 D0 are always 0). (TEMP[9:8], TEMP[7-0])
Which above understanding is correct.
Thanks & Regards
