Resolved! SRAM Memory information
Good morning, I am working with the STM32MP1 and the STM32H7 and will make use of the SRAM memories for critical data. For my application and its security I need more information about the memories. Is there any detailed description or analysis...
How to respond NACK to Master
Hello everyone,I have a application on STM32L5xx, I configuration I2C1 to slave mode,when slave receive first unwanted command code, I want to response NACK to master. I judge the command code in AL_SMBUS_SlaveRxCpltCallback call back function, and s...
Resolved! STM32F4 A/D Input Bias Current
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...
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...
