Part Number: PROCESSOR-SDK-AM335X
Hi,
With reference to the example mentioned above. I plan to modify this firmware to a continuous acquisition at 100 kHz for about 20 seconds. Transfer doesn't need to be real time by can be buffered in RAM before a file write.
Am I likely to face any issues due to any inherent limitation of RPMsg or can I proceed safely? Would EDMA be better suited to this kind of an application?
Looking forward to your inputs.
Thanks & Regards,

Hi,
I am using PGA970EVM with usb2any. I have issue of sine wave frequency. I set 5KHz in WFM Frequency. Then I populate waveform table and click on write. Then clicked on Generate then I am getting 1.812KHz frequency.
I checked at PI(TP16). There also 1.812KHz. What is going wrong.
Thanks.

Hi, team,
I have some questions about Wetting Current Auto-Scaling. Please look into it and give suggestion.
1. If working in Wetting Current Auto-Scaling and current is 10mA or 15mA, how to calculate IN pin average current when DET_FILTER= 00, 01, 10?
2. When working in Wetting Current Auto-Scaling, if INX is set CSI and use comparator to acquire data, how to calculate IN pin threshold voltage?
3. What does below maximum voltage mean? According to CSI current 2mA, IN pin voltage shoule be 2mA*5k=1V<2V, if CSI current is 10mA, it should be 10mA*5k=5V>1.7V.
Thanks.

Hi All ,
How to convert the measured voltage according to the conversion result.
configuration：
1、write: 0x92 0x01,0x84,0x83
2、write: 0x92 0x00
3、read: 0x93 xx xx (xx xx How to convert to voltage value？)

Is there any data how LM4140 performs under 0 C? The exact temperature I'm interested in is -15C.
Thanks!

Hi,
In awr1642 canfd where can i create different message objects in code .
I sent messages with different Message ids. it is sending. is it priority based on id or object number.
if it is on object number in canfd where can i set object numbers . please guide me.
Thanks and regards,

Hi All,
I have a custom board based on Ti's am335x and have Marvell Phy 88E1512 installed on it. The problem I am facing is, if I use Marvell drivers in my QT application to get some lower layer values, the Ethernet Link goes down and I need no power cycle (reboot doesn't work) the device to get the Ethernet Link back.
I tried to debug the issue and found that while accessing register 22 (Page Address Register) in Marvell Phy, link goes down and power cycle is the only way to get the link up.
If I do not change the register values from the QT code, Ethernet works fine.
I have tried to reset the Phy chip from Marvell drivers, but it didn't help.
Can someone please help me to solve the issue?
Thanks,
Part Number: TPS65982
Hi team,
I am working on bringing up a TPS65982 and configure it to sink 15V. However, the controller's I2C lines are routed through an FPGA. Basic idea was to configure the FPGA as I2C master and then configure the controller through the FPGA. But, there is a defect in the FPGA circuit, which renders the FPGA unprogrammable.
Question:
1. Can you please help us that how can we program this controller other than using the I2C pins of the controller?
2. Correct me here if I am wrong, that the initial configuration is loaded from the SPI flash. So is it possible we program the flash memory instead?
Best

I'm trying to make program which toggle pin at given time interval. I was trying to do this with Clock, GPTimer and PWM and here are my results:
I'm trying to figure out why it's shorter than 250 usec? I was thinking it will be same or rather longer. Is something that I misunderstand or doing something wrong? And what can I do to make my program more precise?
Part Number: LP8863-Q1
Hi TI-team
LP8863-Q1 has LED Output String Configuration.
What happens with settings other than Table.5 in the data sheet ?
To be exact that the following settings.
LED0, LED1, LED2, and LED3 are connect.
LED5 and LED6 tied to GND.

Hi All,
I have a custom board based on AM335x processor and CC3100 is attached with processor to get WiFi connectivity, I am using CC3100 SDK for WiFi connections and communication.
My problem is, when I try to ping Google from my board, I get multiple ping failures, is there any way to make it consistent? I think google is the most reliable server and with cc3100 I failed to ping the same :(
Please help me to resolve the same.

Part Number: INA193A-Q1
Hi,
As per the output voltage formula in the data sheet , the output voltage should be zero volts when Rs=open & Is =0 Amps, for the same scenario when the model is simulated in TINA TI, output is saturated to supply voltage of the IC. Please find the below attached simulated file. Could you please help me to know why its not matching with theoretical value.

I have a UART driverlib set up that works fine throughout the entirety of my code both in debug mode and free run (Just loaded onto a chip using Flash Programmer 2). However, I am also using the test commands during my code and use:
RF_runCmd(rfHandle, (RF_Op*) &RF_cmdTxTest, RF_PriorityNormal, NULL, RF_EventTxEntryDone);
I then end up in the WFI and wait for a message on the UART to cancel this. I have no problems with this using debug mode, but if free running the UART interrupt only fires after receiving 3 or more messages (Of size 2 or greater (4 messages if size 1) (I have tried sizes of up to 12 bytes with identical results)) within a second.
I have tried setting the UART interrupt to priority level 0 in case there was some background interrupt I cannot see which causes this problem by constantly overriding the UART interrupt.
Here is the initial set up for my UART:
uart_private.handle = UART0_BASE;
PRCMPowerDomainOn(PRCM_DOMAIN_SERIAL);
while (PRCMPowerDomainStatus(PRCM_DOMAIN_SERIAL) != PRCM_DOMAIN_POWER_ON)
;
PRCMPeripheralRunEnable(PRCM_PERIPH_UART0);
PRCMLoadSet();
while (!PRCMLoadGet())
;
IOCPinTypeUart(uart_private.handle, MODULE_UART_RX, MODULE_UART_TX, MODULE_UART_CTS, MODULE_UART_RTS);
UARTDisable(uart_private.handle);
while (UARTBusy(uart_private.handle))
;
uint32_t config = UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE | UART_CONFIG_PAR_NONE;
UARTConfigSetExpClk(uart_private.handle, SysCtrlClockGet(), 115200, config);
UARTFIFOLevelSet(uart_private.handle, UART_FIFO_TX1_8, UART_FIFO_RX1_8);
UARTEnable(uart_private.handle);
IntPrioritySet(INT_UART0_COMB, INT_PRI_LEVEL0);
UARTIntRegister(uart_private.handle, &UART_Read);
UARTIntEnable(uart_private.handle, UART_INT_RX);
while (UARTBusy(uart_private.handle))

Part Number: MSP430FR2433
This thread shows the possibility to view and change variables via a serial interface (UART) during the program runtime in CCS debug mode.
Some time ago, I already made the ProgramModelUart aware and asked for a possible change in the CCS. After some research I noticed that the backchannel Uart does not have the required transfer speed on various launchpads. In detail: If something is sent via Uart from the MSP430 of the Launchpad, a significant delay of the transmission in the debug-mode is to be determined. This led to the described malfunction in this thread: e2e.ti.com/.../700089
With an external serial to USB adapter, however, the transmission speed is adequate.
The described ProgramModelUart should be very interesting for many users / developers on the MSP430 platform, since similar to, for example C2000 controllers, it is possible to view and change variables in the debug mode during runtime. Ideal, for example, for setting controller values.
For this I have taken the subject again and put a small example based on a MSP430FR2433 Launchpads on Github.
I'm hoping to show some people a good debug option for MSP430 controllers.
Regards,
Benjamin.
PS: By the way, this function can of course also be transferred to a C2000 controller ...

Hello,
I am trying to solve motorware lab 13b, which is position sensing lab. Now the lab is working perfectly. I have generate a speed sample graph. but now i want to calculate the revolution moved by the rotor from the graph by calculating the area underneath the curve as shown in figure. but problem is x axis is in samples. how can i get time information from the sample so that i can calculate the area underneath?

Dear Arthur,
one question if we want that inrush be 500mA and the CL is 280uF (Vin = 5V9
We get the calculation SR_ON = 1785V/s.
in your Table 1 in DS you only have for 780V/s = 100nF
How can i calculate the CSS for SR=1785V/s ?
Best Regards,
