Posted on August 01, 2017 at 16:03Hi ForumI'm trying to implement USART Rx of variable, unknown length messages at a 1Mbps baud rate through DMA. I would like to minimize the latency from receiving to consuming the data, so I'm trying to do this wit...
Hi , I encountered an interesting problem while I was trying to calculate the Bit-Banding Address of GPIO registers .The peripherals working on AHB2 and AHB3 busses are overflowing when trying to calculate their bit-banding map .. For Example ;I wan...
Hi,It says on page 107 of stm32f777bit6 manual that:"Each OTP data block can be programmed until the value 0x00 is programmed in the corresponding OTP lock byte."I understand that OTP is supposed to be one time programmable but the above statement se...
There is the Figure 80 "DMAMUX block diagram" in the STM32F743 Reference Manual (RM0433), which shows that there is 'm' number of dmamux_evt signals, where 'm' is 16 for DMAMUX1 (the number of DMAMUX1_CmCR channels).The Manual only describes the dest...
