CCS/TMS320F28069: Using - STDIO - Sometimes sprintf is incorrect...
Part Number:TMS320F28069
Tool/software: Code Composer Studio
Hello,
My app is doing the following as a debug print about once every second:
sprintf((Uint8 *)&debug_string[0], "HRC1: H%lu, %lu, L%lu, %lu\r\n", xMessage.int_HRC1pulsewidthhigh0[i], xMessage.frac_HRC1pulsewidthhigh0[i], xMessage.int_HRC1pulsewidthlow0[i], xMessage.frac_HRC1pulsewidthlow0[i] );
USBBufferWrite((tUSBBuffer *)&g_sTxBuffer, (Uint8 *)&debug_string[0], strlen(debug_string));
I'm using the terminal in CCS to see the debug print - also - the app will run for a while and will eventually crash; usually hitting an ESTOP statement in an unhandled vector. (Only happens when I enable this debug priint output.)
The following is an example output: (<== marking the issue)
HRC1: H47, 61566, L48, 3970
HRC1: H61566, 47, L3970, 47 <==
HRC1: H47, 61566, L48, 3970

HRC1: H47, 61682, L48, 3854

Any advice on this appreciated.
Thanks In Advance,

Linux/AM5728: AM5728 interface with Alliance memory (AS4C512M16D3L) DDR3L
Part Number:AM5728
Tool/software: Linux
Hi,
With reference to AM5728 EVM schematic, we have designed our custom board with AM5728 to suits our requirement. But, due to non availability or more lead time of Micron part (MT41K512M16HA) DDR3L is not available for us. hence we have selected pin to pin compatibility of Alliance memory (AS4C512M16D3L) DDR3L.
To make it work i.e AM5728 interface with Alliance memory (AS4C512M16D3L) DDR3L what are the necessary changes required in processor linux SDK, U-boot, DDR config, Emif files etc.
please guide us since these are BGA's once assembled we cannot re-solder it.
As per AM5728 EVM schematic processor is interfaced with Micron part DDR3L, we have to go for micron part for compatibility of drivers or any make is acceptable.
regards

DRV135: DRV135 or alternative for differential mic signal over 300m
Part Number:DRV135
Hi,
In my application a differential MEMS microphone signal is to be driven over max. 300m where a differential ADC is used to sample it. DRV135 is a single to differential line driver. Is there similar drivers for differential input or is any differential amplifier suitable for my requirement? Is an amplifier at the receiver end like INA134 enough without an amplifier at the sensor end?
Thanks,

TRF7960: TRF7960 SPI do not feedback data to MCU
Part Number:TRF7960
We run TI example code in MSP430G2553 to operate customer TRF7960 board, G2553 has send read command by SPI to TRF7960, however TRF7960 do not replay any SPI data.
I try to measure TRF7960 pins signal, VIN / VDD_RF / VDD_PA is 3.3V, EN is 3.3V, OSC_IN / OSC_OUT is 0.5V~1.5V crystal waveform, however I think it seems wrong for VDD_A is 0V, BAND_GAP is 0V, VDD_X is 2.3V, VDD_IO / IO1 / IO2 are 2.3V because pull up by VDD_X. Could you please help advice the possible reason to cause such issue?

LMX2581: PLL locking and phase noise issues
Part Number:LMX2581
Dear Sir, Good Morning.
I am facing problems locking issues with LMX 2581. I want to use it as a synthesizer for generating multiple freq. (one at a time) 950 MHz, 990 MHz, 1030 MHz, 1070 MHz & 1110 MHz using 20 MHz Oscillator input. The RF output setting of 950 MHz freq. comes 948.62 MHz that is also not locked . I have used the the 3 LDO for supply of LMX 2581 (LP2985) and presently for testing i am giving 20 MHz from signal generator around +
3 dBm at Oscillator input. The phase noise performance is also very bad. I have checked the circuit as per your evaluation Board. please help

We are working on one project which has the CC2640 module but we can't flash it an receive some error.
Till now we have already tried with UART, 4-pin JTAG IAR i-jet, and J-link but it was not flashed and show error every time.
Kindly help us to solve this issue and it would be great if you can share the steps to flash using i-jet or J-link(available with us)

LM5116: Minimum input voltage for stable output
Part Number:LM5116
Hello, I have made the boards with LM5116 (9-18V input, 7.5V output) and they are working fine, however with lower input voltages the output voltage drops.
For 9V I get around 6.8V output instead of 7.5V, if I go below 9V it drops even further. The current consumption is rather low (a few amps).
What may be the reason for this ?
What is the minimum input voltage that should ensure nominal output voltage ? I know linear regulators have a defined voltage drop IN-OUT but how is the situation with such a DC-DC converter ?
And what happens if the input voltage is very low (for example 6V) - if the UVLO is not used ?
The output should follow the input voltage or it will drop further or what will happen ?
Thanks,
Mihai

66AK2H14: Serdes ref_clk input
Part Number:66AK2H14
Hi,
I have read the SPRUHO3A Serdes user guide document, and was surprised by the restrictions applying to REF_CLK values. Specially given all the MPY/RATE_SCALE facilities available through registers.
For example table 7-1 accepts 125 MHz input frequency for SRIO Serdes while Hyperlink Serdes does not (see table 8-1) , nor 10Gbe serdes.(table 11-1). The most restrictive being PCIe serdes, only accepting 100MHz input frequency (table 10-1).
At same time the document admits that other configurations might exist and that we should refer to a "configuration list" inside TI MCSDK.
Here are the questions :
- Could you please send me the above-mentioned "configuration lists " because I don't know where to find it.
- Are the limitations only due to currently available software, or are they resulting from hardware reasons ? For example how explain that it is not possible to achieve 2.5Gb/s PCIe from a 125MHz input clock, the Fq ratio being so straighforward ?
With best regards,
Bruno

CCS/TMS320F28027: Guide me through how to use piccolo micro controller I'm very new to this
Part Number:TMS320F28027
Tool/software: Code Composer Studio
Hi,
I'm very new to the use of a TI Piccolo microcontroller, I'm using it to drive one of the Mosfet which is used in a converter circuit of a battery charging. I'm struggling to find a way to do this, I have downloaded code composer studio as I'm new to this facing difficult to use it. Also, I don't know how to program this microcontroller to drive the MOSFET's through PWM and measure the various current and voltage value across a converter circuit through ADC pin. Any reference link and guide will be very helpful for me,

PACKET-SNIFFER: How to set up simple communication
Part Number:PACKET-SNIFFER
Good Morning,
I'm starting an RSS analysis study on zigbee networking.
I still have little knowledge in the area.
I bought 5 CC2531 USB Dongle for first:
Learn to communicate with the notebook.
Learn how to create a network.
Learn how to read network data using Python.
So on and on.
I have already received the modules and installed Packet Sniffer as
"CC2531 USB Evaluation Kit Quick Start Guide" Installed version was the 2.18.1 on my Windows 7 64 bit.
When I precede the star (Choosing the IEEE 802.15.4 / ZigBee protocol) in the "Capturing Device" tab I have the recognized CC2531 USB Dongle (USB Device ID = 5235) - CC2531.
On windows in device control, appears Cebal - USB Dongle CC2531.
How to set up simple communication? Which options to select in the other tabs (Radio Configuration, Select Fields, Packet details, Address Book, Display filter, Time line).
In both CC2531 USB Dongle Led 2 is green and is constantly on.
I would greatly appreciate the help.

My current debugger set-up:
When measuring the output of the AUX, TGTSUPPLYOUT I measure apporximitely 0.014 V. I am still able to connect to the target somehow, but it immediately enters an exception state due to no target power.
Are there any settings I am missing to activate this functionality?
