I would like to know if the SPSRF could work for us?can it pass UART/SPI/CAN/etc. side to side?thanks
For instance STM32H750VBT6 has many timers, but CubeMx does not show where their outputs would go. I don't want to mess (enable all of them) an existing design just to see where timer output are.
In STM32F098CC/RC/VC pin definitionsit is saying that PB4 has USART5_RX for LQFP48 but when i looked at PB4 AF's in Table 13. Alternate functions selected through GPIOA_AFR registers for port A , there is not USART5_RXand AF4 is empty(even there is n...
Hi againI'm using STMG071 with 2*DAC. I need them as negative inputs to COMPx.in order to use PA4/PA5 for other purposes – I set DAC1->MCR =0x00030003; so DAC will not be output to the pin (PA4/PA5).Yet – as soon as DACs are enabled (DAC1->CR 0...
My compiled program could be around 50MB. I am browsing internet several days to find a way how to run it at STM32F769I-DISC1. So far I just configured SDRAM1 128MB. My questions are:1) Can I compile the program and in Debug mode copy it to SDRAM an...
HiI have (had) a working project with an EXT interrupt which was wired to the CS pin of a SPI bus.Although it was working I had various bugs, particularly a timer interrupt, which TDK helped me resolve earlier.I've had great success with SPI master, ...
I need to generate an interrupt if a low level is hold more than specifical time.I wanna achieve that executing Timer reset and start counting on failing edge, stop on rasing edge, if the duration is larger a compare register, a interrupt generated a...
I'm sending and trying to receive 5 bytes. If I run the peripheral at 3MHz all is well. If I run at 6MHz I miss receive bytes. If I break and inspect hspi4.RxXferSize I can see this will be stuck at 2. The TxXferCount has counted down to 0, and so th...
Hi guysSo I am developing a small PWM generator around the F334R8, it's overall extremely simple. All the work is done with another MCU sending data on SPI.On the F334R8, an EXT interrupt is called when the CS line is pulled down. From there the F3 l...
