STM32L0C8T6 failed to communicate with M24C02 through IIC
STM32L0C8T6 failed to communicate with M24C02 through IIC，iic uses cubemx default configuration，The relevant code show as below：#define ADDR_24LCxx_Write 0xA0#define ADDR_24LCxx_Read 0xA1#define IIC_BufferSize 256uint8_t IIC_WriteBuffer[IIC_BufferSi...
Resolved! Not sure to whom to address my question: Question about Virtual Com-Port-Driver 1.3.1.0 installed on WIN10. The manager states "STMicroelectronics Virtual COM Port (COM 6)". But my attached ext. divice, which I want to access only accepts port 4!?
How can I change the driver to port 4 or how can I install the driver additionally for port 4? *Edited by moderation: please don't mention your email address publicly on this forum*
Looking for the source of the STM32F1xxx product
I want to load the source of the STM32F1xxx product for benchmarking.Please tell me the required environment.I want you to teach me both software and hardware.
STM32F103 SPI Slave strategy
I use STM32F103C8T6 as SPI slave and want to send data on request by master.The master sends to the slave a byte, which has to be used to decide, what has to be doneor what data data has to be sent to the master, and a fill byte which is neededto shi...
Resolved! Is it possible for slave to read on 1st clock edge and master to read on the 2nd clock edge for SPI?
Upon reading the user manual for the STM32F072, it seems like it is only possible for the slave and master to both read on the first edge or both read on the second edge. However, I am trying to interface with an ASIC in which the ASIC(slave) reads o...
Is there a HAL example of a memory to memory, or memory to peripheral DMA operation triggered directly by a TIMER event (not via a timer ISR) on the STM32H7?
I've read a ton of app notes, the STM32H7 reference manual, posts here, and I can't figure out how to have the timer UP event trigger a DMA operation. I'm sure this is obvious to someone with more understanding and could be gleaned from other STM32 m...
STM32G474 - UART interrupts keep firing when they should not be enabled
I am using USART2 on the G474 processor, and I only want the TXE and RXNE interrupts to fire. To do so, I wrote the following: //Enable/set the TXE and RXNE interrupt bits __HAL_USART_ENABLE_IT(&husart2, USART_IT_TXE); __HAL_USART_ENABLE_IT(&husar...
Resolved! Search engine on the website: is it operational?
In the last 2 days I can't get any results using search engine on the website. For instance, when I type in any STM32H743II code there is only a message like in the picture below. The same situation is for any acronyms or Doc Ids. Is it only a proble...
