Resolved! Output Capture not working to blink LED on NUCLEO-C031C6
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...
Discovery L0538 UART2 RX Pin Stuck Low?
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...
Resolved! The difference between Macronix mode and Macronix RAM mode in OCTOSPI Memory type configurations
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...
Resolved! ST BLE Toolbox: How to use the environment
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...
Resolved! STM32C031C6 Timer Input Capture
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...
Do I need to compile different binaries for two MCUs in the same family that only differ in flash size?
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...
Resolved! DFSDM Output resolution
When I use DFSDM, I configure FOSR= 256 ISOR=1 and the output is outside the range in the reference guide +-16777216
In the case of STM32U575ZIQ, Can I use an external DMA (and not the internal I-DMA) to interface the SDMMC card?
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 (...
Resolved! ADC output suddenly becomes constant
Hello,I'm using the ADC on a STM32G431 to read 5 voltages at 20kHz. Everything works well, but suddenly the 5 channels "get stuck" or freeze, i.e. the value they measure becomes constant even though the voltages on the input pins still fluctuate. Som...
