I'm working on a STM32C071RB, which I've managed to generate PWM pulses as desired. However, I try to more than once while the chip is running, it stops working.My main.c file:#include "main.h" #define PWM_HI (12) #define PWM_LO (6) TIM_HandleType...
Hello, I'm working with a STM32G0B0CE part. I believe that the TRM definitions for RCC_CCIPR2->USBSEL are incorrect.I was having trouble with USB, seemingly related to clock selection. I noticed in the LL HAL headers the following:#define LL_RCC_US...
HelloI am trying to get the STMN32G431 processor to do what I want.If I set the baudrates 500kB / 2MB and a samplepoint of 87.5% for both and send a CAN packet with FDF and BRS I get after 3 ms:LastError = Recessive Bit Error and 8 Tx errorsand 2 ms ...
Hello all, This is my first post on here, if I am in error at any point please direct me to any relevant posting guidelines. I am developing a sender-receiver solution involving two STM32H753 microcontrollers, both on ST's NUCLEO-STM32H753 boards. I ...
Good day.According to the description in RM on STM32F103, in Control Transfers:"A USB device can determine the number and direction of data stages by interpreting the data transferred in the SETUP stage, and is required to STALL the transaction in th...
Hello, I'm working with the STM32U575VGT6 as my primary MCU and need a USB-C DRP PD IC. I'm considering the TCPP03-M20 or STUSB1600AQTR. My question is, when the PD operates in sink mode (during charging), we intend to turn off all power supplies, in...
Peripheral: QSPIBug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for athreshold leve...
Hi,I need to run my application in the external flash, as the size of the internal flash is very less for the stm32h7s78-dk board. I have turned on optimizations as well, but i need external flash configuration. probably XSPI1, XSPI2 what all the thi...
Hi, I'm getting started at embedded programming, I've got this blue pill board having the STM32F103C6 MCU and ST-LINK v2 programmer.Here's my code, just to light up the LED on port C 13:#include "stm32f10x.h" int main() {RCC->APB2ENR |= (1<<4); GPIOC...
Hello Team, We are planning to use STM32H7S7L8H6 in our new design.We want to interface IS21EF04GP-JQLI-TR eMMC with STM32H7S7L8H6.So, for this STM32H7S7L8H6 required only 3.3V supply right?It will be to communicate with eMMC IS21EF04GP-JQLI-TR. So, ...
