I'm not able to find a spec in the STM32F446 datasheet for minimum A/D input bias current. Does anyone know where I can find this info? I need to sample the voltage from a high resistance potentiometer and it would be handy to know if I need to buf...
I am trying to implement output capture using the LL APIs but cannot get it to blink the LED every one second on the NUCLEO board, however, I cannot get it to blink at all. Is there a register I missed?Here is my code:#include "stm32c0xx_ll_bus.h"#in...
Using a Discovery L0538, and want to make use of the 2nd UART (really only need the RX on pin PA3). I noted in the User Manual that to disable the onboard touch sensor and use this pin, I need to jump solder bridge SB24 (which I did, alng with the ot...
I want to use MX25UM51345G on STM32L5. When configuring the Memory type, I found these two mode:001: Macronix mode, D1/D0 ordering in DTR 8-data-bit mode. Regular-command protocol insingle-, dual-, quad- and octal-SPI modes.011: Macronix RAM mode, D1...
Hello,I am working with the Nucleo Bluetooth boards (NUCLEO-F401RE + NUCLEO-IDB05A2) and I want to test some custom code I'm writing to make sure I understand how to use the X-CUBE-BLE software package. To do this, I am trying to use the ST BLE Toolb...
I'm attempting to do a simple Input Capture using Timer1. I thought as a start I would generate a single 200uS pulse using a Signal Generator and use Timer1 to detect it. I can't seem to get the capture to work no matter what I do.I tried using HAL a...
I have an STM32F427VGT6 and a STM32F427VIT6 which only differ in Flash size. I have firmware that works fine on the variant with smaller flash size. Do I need to recompile it for the larger variant or will I be able to flash it as is? I am asking bec...
When I use DFSDM, I configure FOSR= 256 ISOR=1 and the output is outside the range in the reference guide +-16777216
Basically, when I use the IDMA of STM32U5, there is a significant delay happening while communicating with the card. And if I do the same by using STM32F4(which uses general DMA), then there is not such a huge delay. After checking other parameters (...
