Hello All !
I am a Mechanical Engineer and totally new to STM32; but the assortment of attractive features on these boards tempted me to get one and start my Project. I need to interface a DAQ for IEPE Sensors. I found found one on AliExpress, similar to the TI Evaluation Board they have on public domain, the TIDA-01471 using the TI ADS127L01 ADC. The DAQ has a SPI output. PDF is attached herewith. The same has a Header of 22 pins. Pins are as;
VIN | 1 | 2 | VIN |
GND | 3 | 4 | GND |
OUT-F | 5 | 6 | SOUR-EN |
S-SYNC | 7 | 8 | S-DIN |
S-SCLK | 9 | 10 | OSR0 |
OSR1 | 11 | 12 | START |
DRDY | 13 | 14 | DOUT |
DIN | 15 | 16 | nCS |
SCLK | 17 | 18 | GND |
RST | 19 | 20 | HR |
PGA-2 | 21 | 22 | PGA-1 |
Pins relevant to ADC are 10, 11, 12, 13, 14, 15, 16, 17, 19, 20, 21 & 22.
Presently do not have the board either; it is on it's way. Just planning it. A word document is also attached whereby I have been sorting out the solution matrix. Please correct me where I have erred.
Never used a STM32 board before but I am an avid learner. Therefore would need all help and patience from the friends. To begin with, can someone please help with the idea that TIMERS / INTERRUPTS also need to be involved in mapping the above parameters within the STM32 ? How many TIMERS and their sequence. I am unable to work it out at the moment.
Enough for the moment. Thank you all for the audience.
Sincerely,
Muhammad
