I am a student at Bilkent University and I have an internship project where I will be using a serial to ethernet converter to download firmware into an STM32F4 using tcp/ip protocol. I am using the IP address of the converter to make a virtual COM po...
I'm having trouble using ADC with DMA. It is working correct, I'm getting the correct result. But DMA is corrupting another data which is not related with DMA in runtime. I'm also using Ethernet, because of it, I can not disable D-Cache.I do my Ether...
I have a system with an STM32H74A3, which uses one SPI port for different slaves which use different SPI modes.One Slave needs Mode 3 (Pol.High/2ndEdge) and 8 Bit Data size, the other needs Mode 0 (Pol.Low/1stEdge) and 16 Bit. Clock Speed is the same...
Any help is highly appreciated!
Hi, I am curently working on the STM32H747. I need to have the CM7 booting while the CM4 is not. Then after, the CM4 BOOT is triggered by the CM7.Using STM32 cube programmer, I am able to disable the BCM4 bit of the SYSCFG_UR1 register.The required s...
I'm using stm32f103c8t6 to control tft screen. I tried to use stm32f030c8t6 to conrol tft with same library but screen is always black. What can be the reason ?
We are using stm32g431c8t6 and firmware update is performed by another MCU placed on the same board, via UART bootloader.During development everything was fine - but after production, on some chips (~10 out of 50) bootloader behavior is undocumented:...
According to AN4759 , the RTC v3 (or, as they call it there, RTC3) - in 'G0, 'G4, 'L4P5, 'L41x, 'H7A3 and some of the more specialized series, has a Binary mode as an alternative to Calendar.JW
RM0455, rev. 6, says reset state of SYSCFG_PMCR is 0x0F00 0000.But STM32H7A3ZIT6Q, rev. Z, shows 0x0300 0000 instead, i.e. PC2 and PC3 switches closed. not open. Does this depend on package as PC2 and PC3 are not bonded out for this particular packag...
