Hi!I know how to measure 4-20mA sensor with STM32 by using a 160-165 Ohm resistor as a shunt resistor between ground and analog input of the STM32, and then apply 4-20mA into the analog input.But at 4mA, I gout about 0.6V into the ADC and then I losi...
Hi, I have 50Hz sinewave with 660mVp-pk, should i connect this to SDADC analog input? It can measure negative cycle of the sinewave? i.e. If i configure SDADC as single ended zero reference mode then it can measure negative cycle of the sinewave?Na...
I am running both SDADCs on a STM32373C-EVAL evaluation board. One of them is giving me the correct values from 0-65.535 but the second one is giving me 0-32.767 on the same voltage.I have configured them using the Cube IDE and Hal. They are set up e...
Hello all,I thought this is a straight forward thing but for me it turned out not to be...What I want to do is simply using SDADC1 and SDADC2 and perform a regular conversation at a time in multimode. I configured both in CubeMX and tried to sample b...
Hello.Reffering to AN4207(Doc ID 023945 Rev 1) Single ended zero reference mode (Page 9):This mode injects an input common mode of half scale to the ADC thus maintaining the dynamic range the same as in differential mode (-32767 to +32767). In this m...
Hi!I'm trying to make 16-bit ADC measurement works but I have some trouble understanding the argument Channel. First I have these SD-ADC channels.SDADC1 have:IN4 = Single zero referenceIN6 = DifferentialIN8 = DifferentialSDADC3 have:IN6 = Single zero...
Hi,We have a problem with SDADC on STM32F373CCT6. We are using two SDADC Analog pins to measure the voltage. Even through the voltage on the both the Analog MCU Pins SDADC-1 and SDADC-2 are same, the digital output voltage and ADC values from the MC...
Hi, I'm using STM32F373 for a biosignal measurement project, and I need some help writing firmware to automatically update the SDADC channel gain during execution.For example, I'm sampling at 100Hz, and after every 100 samples, i want to change the g...
Trying to get best of STM32F373CCT6 & its differental moded SDADC1 for a pressisios bridge type sensor.Datasheet's say that the SDADC speed limit is 50kS per second.Ive reached only 68uSec (~15k) for thisHAL_GPIO_WritePin(GPIOA,GPIO_PIN_4,GPIO_PIN_SE...
Hello,I am working on the stm32373C-EVAL but I can't get the SDADC to give me satisfying values.I am following the UM1786 "how tu use this driver" instructions on p°594:I fill in the HAL_SDADC_MspInit(), the HAL_ADC_Init() is used, I call HAL_SDADC_P...
