Usage of Comparators with PWM Generation
I am trying to design a digital SMPS with an STM32G0.ST has lots of literature stating that the comparators can be used to control the duty cycle of the PWM from a timer.I understand the use of a comparator to detect a fault and output to the BKIN in...
Resolved! STM32G431C6 fails to power up sometimes.
I designed a board that uses the STM32G431C6 and is intended to connect in a chain with other similar boards, but I am having problems when powering them up. They turn on and work fine sometimes, but sometimes boards won't turn on. Each board I desig...
9 bit SPI for TFT
Hi, I have a TFT screen that is using 3-wire 9-bit SPI (DC bit as 9th bit) has anyone got and experience or examples of this with HAL? I think I have it explained below, the problem is when I test on the oscilloscope the SPI data is reversed as MSB i...
Resolved! GPIO pins won't RESET low (always high)
I took the default STM32F101VFTx, enabled PB8 & PB9 as GPIO Output, and then tried to pull the pins low. I am having an issue that caused me to create this isolated test. Configurations, code, and scope on the pins below. Repo for this test case ...
Resolved! 4 DACs, 4 audio rate sawtooth waves with SMT32G4
Hello,I am looking to develop with the STM32 microcontrollers for the first time and was hoping to get some help. I need to create a device capable of outputting 3 separate sawtooth waves that are individually controllable to synthesize audio based o...
Resolved! Hard Fault exception is occurring while programming in FAST mode for saving data in stm32G0 Memory
Hi community,I am observing Hardfault exception when trying to program internal flash of stm32g030k6t6 MCU in FAST mode . is there anyother FLASH registers i need to enable ?I have attached the code here static void write_data_to_application(void) { ...
How do I synchronize received UART data ?
I am trying to receive a frame containing 10 bytes of serial data, each frame is transmitted at a 100ms rate.However, as the UART can start receiving the 10 byte frame at any point in time, the received data is becoming out of sync. How do I sync the...
Resolved! using several ADC
Hello,I wonder if it is or it is not possible to use more than one ADC independet of each other. My problem is as follows: I want to use ADC1 and ADC2 in independent scan conversion nothing works anymore. My code work for ADC1 alone or ADC2 alone,...
Resolved! Flash via I2C bootloader problem for STM32G0B1KBU6
Hello,We encountered a problem with the internal Bootloader of the STM32G0B1KBU6 MCU.ConditionsFirst, the option bytes are set with an STLINK-V3 programming adapter (SWD interface) and CubeProgrammer (2.15.0) according to Pattern 11 of AN2606:nBoot_S...
