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...
Resolved! Why does AN5050 say PSRAM not supported on STM32L4Rxxx?
I'd like to use the STM32L4R9ZG microcontroller along with a HyperRAM memory such as the ISSI IS66WVH8M8BLL. I was reading through the ST application note AN5050 "Octo-SPI interface on STM32 microcontrollers" to familiarize myself with the process. O...
Resolved! STM32L4S7ZIT: Can FMC be used with DMA?
HI All,I plan to use STM32L4S7ZITx cpu. I need to work with LCD screen which has parallel interface and connected to FMC. It works fine on demo board but i would like to offload the CPU. But i am not sure if FMC can work with DMA.I checked the follow...
STM32G030J6M6, SPI
Hello.Is it possible to use hardware SPI with STM32G030J6M6 (SO-8)?SPI1 use PA1 (NRST pin) for CLK without remap possibility.SPI2 also use PA1 (NRST pin) for CLK, but has CLK remap to PC14. In that case no MOSI pin.I try to use SPI1. PA1 configured...
