Internal flash storage issue on STM32G0B1
Good day,I am writing firmware for a custom board using the STM32G0B1KET6 and am experiencing issues related to writing a serial number to the internal flash.As far as I can tell, this MCU has 512 KB of flash split into 2 banks of 128 pages (each pag...
Generate two 50% duty PWM signals with 90° phase shift using a single timer
Hi everyone,I’m trying to generate two PWM signals with 50% duty cycle and a 90° phase shift, to simulate an A/B type output.I managed to achieve this using two different timers and adjusting the compare values, but I’d like to know if it’s possible ...
Resolved! STM32U585 jump form application to STM32 bootloader will not respond to FDCAN messages
I’m running into a strange issue when trying to jump into the STM32 bootloader.I’ve built an FDCAN bootloader flasher using an STM32H7 along with a Windows host program. This setup allows me to reprogram both virgin and already-programmed. To do this...
ADC Fluctuation
Hello,I have a ADC clock running at 96MHz prescaler divided by 10, 12bit, Sampling time 47.5 Cycles. I am just trying to sample this DC volgtages. I have a battery that has around 20Volts, and I am stepping this voltage down using the voltage divide...
Resolved! STM32H725VGH6 / Direct SMPS Supply / VLXSMPS Connection
Hi,We are using the STM32H725VGH6 MCU and are plannign to use the internal SMPS for VCORE.With regards to the connections required for the VLXSMPS pin, I would just like to confirm that a 220pF capacitor is required on this pin in the "Direct SMPS Su...
STM32G030C8T6 readout protection doesn't work
I tried to set readout protection via ST-LINK CLI - it's enabled and disabled correctly, but after RDP=0 I can't erase/write chip - I've got an error on write operation. Tested on 2 boards and both boards have same behavior. e:\STM32 projects>"%PROGR...
Ultra Low Power Application without USB - what to do with VDDUSB?
Hi We are working on a project based on the STM32U073CCT6. The USB interfaces is not need. How should I connect the VDDUSB pin in order to minimize tthe power consuption? Is it Ok to connect it do GND? BrGilberto
Resolved! STM32H747-DISCO Core-Lock Problem
Hello,I’m using the STM32H747. When I set the RCC power source to RCC → Power parameters → Supply source = LDO, the core locks up; if I select SMPS, there’s no issue.When I set CM7 to its maximum clock frequency (480 MHz) and CM4 to 240 MHz, the tool...
