Currently i am writing my own MCAL drivers for G4 MCU's and i dont understand interrupts for timer channels 5&6. Lets assume Timer 1 where you can check interrupt status of CC of channels 5&6 in TIMx_SR on bits 16&17. But there is no mention about ac...
Hello,I'm refering to DS14121 Rev 1 of STM32H573xx. - "Figure 1. STM32H573xx block diagram" shows 4 32 bit timers (TIM2, TIM3, TIM4, TIM5)- "Table 2. STM32H573xx features and peripheral counts" says there are only two.Where can I find trustworthy inf...
Hi everybody I'm developing a simple bootloader which run an application loaded in flash memory at the address 0x80200000. The application alone works correctly but when I use the boot the app doesn't run. This is the code of my boootloader #defi...
Hi. I am building USB PD sink device. I would like to use built in STM32 UCPD controller.I've created test application in STM32CUBE based on AN5418. It works properly but i want to add PDO read functiinality.All tutorials say that all info about port...
Hi， I'm using STM32G431 to drive my SPI screen. Due to the high cpu load, i decided to change the IT sending mode to DMA. After putting a little changes on code, it doesn't work any more, and i have confirmed it will work again once get it back to IT...
Hi,Master:platform: STM32G070CBphenomenon:When the MCU is empty (without any program), connect an external pull-up resistor 10K to the adjustable voltage source on the PA4 pin, adjust the voltage in the range of 4~18V, and find that the maximum clamp...
Hi,Anyone know where I can find memory benchmarks on using the different type of external memories on the STM32F469/79 ?How slower is the PSRAM on FMC or dual Quad SPI compare to internal SRAM ?thanks
Hi,(Sorry, I'm not sure where best to post this)After digging into issues with SPI hardware CRC on an STM32F103, it seems like the SPI HAL functions are not clearing the CRC flag before starting a new SPI transaction. I think they should be calling _...
Hello, is there any simple example for (STM32G0B1CBT6) or similar where I can simply filter int genration for eg. only for 0x505 id in standart mode. I tested many samples and I believe that there must be some bug in IDE. This is static void MX_FD...
Hello,I have a Nucleo-F439ZI as SPI master connected to four Nucleo-F030R8 SPI slaves.Initially, the SPI communication was working perfectly fine. But after a while, the master received only zeros on MISO line even though, the slaves where sending da...
