STM32F446ZEJ6 Daisy Chain JTAG
Hello,I am currently working on a project where we have daisy chained the 5 Pin JTAG of STM32F446ZEJ6 with a TI microprocessor AM24x series. My question is that is there a way I can get a configuration file for the STM32 to create a new custom config...
To Create Three PWM signals using one TIM1 with 120 phase shift
Hello,I'm using a STM32F303RE to create the PWM signals.I need to have 3 PWM signals plus their complementary outputs with same pulsewidth and a phaseshift of 120° between them, see picture below.Hands-On with STM32 Timers: Internal Triggering System...
PLC Likes ON-PULS
I would like to generate a pulse by timer.Idle state: GPIO-PIN HIGHafter internal trigger: GPIO-PIN LOWafter 1us back to GPIO-PIN HIGHi have try by PWM, OC and one pulse enabled mode.but my pulse is starting after 1 us.
Need support in using PSRAM as internal RAM using memory mapped mode using QSPI
Hi,I have been working on, interfacing PSRAM(APS6404L) with NUCLEO-H563ZI board.i'm able to perform read and write operations using QSPI and able to create the memory mapped mode. I have modified the Linker script,i'm able to declare variables on ext...
Migrate from STM32F401CCUx to STM32F103C8T6
I've done a long search on the Internet but only found the migrated STM32F103 to the STM32F4 series, not vice-versa. So I'm asking anyone who can help me. To be specific I am going to try this project from GitHub but in my case, I'm going to use STM3...
Resolved! STM32H5 SWO debugging
Hi, We want to use now the STM32H5 for future projects. In the past, we used STM32F4 with enabled SWO for debugging. Is there any example available to get this feature working for STM32H503? Would be great to do it on register level to be independent...
Flash Memory
We are using STM32F373VCT6 Microcontroller for our application and we want to use an External Flash Memory of 1MB with this controller. Can you suggest some NAND/NOR Flash memory of 1MB, that supports SPI/QSPI and is compatible with this controller a...
H735 flash writing vs. interrupts and ... what?
Heyho FLASH experts!within the last few weeks I was able to get an ethernet bootloader running on a H735 discovery kit.Internal flash is partitioned into area starting with the bootloader (256kB, including ETH), then comes the application (rest: 768k...
STM32F767 NRST held to VSS
I have a custom PCB based on STM32F767 which has been working for about 2-3 weeks, through about 100 re-programming cycles (doing debugging). Now, after last attempt to flash, the NRST pin is "stuck" to VSS. I lifted the pin of the trace, e.g. NRST p...
