Any chance for a STM32F720?

Hello,the STM32F730 in packages with 144 and more pins offers a high speed USB phy. The price for that chip would make it a favourable solution for USB HS. BUT the chip has crypto modules that require export restrictions. A variant as STM32F720 with...

hello, stm32f407 's code is working while debug I can see the data to the registers but I do not have any reaction when I load the card I would appreciate if you help ..

STM32F103 won't wake-up from standby when using RTC Alarm

I can wake-up the STM32F103 from standby mode with an external signal on the PA0 pin. Also, the RTC alarm produces an interrupt when the MCU is not in standby mode, but when the MCU is in standby mode I cannot get it to wake-up with the RTC alarm.

My STM32F446RE CAN controller declares a message on the bus (transmits SOF), but then never transmits anything else in the frame (bus just stays idle). Why is this?

I have implemented a CAN controller on the STM32F4 where it successfully transmits a SOF bit, but then the bus stays idle for the rest of the message. The values loaded into the registers are all correct and verified that they have been successfully ...

Hello to All, Please, could someone provide the C code algorithm (or tell me where I can find it) to calculate the same CRC 32 computed by HW in the micros STM32L1 and STM32F3? Thanks a lot

How to increment the Independent and Window Watchdog's maximum timeout value?

I am using an STM32F411 MCU and I'm trying to set up a watchdog that interrupts, executes my Contactor_Off function, and does an MCU reset if the software doesn't reload the Watchdog counter after 4 minutes, or reloads it way too fast. I thought of u...

STM32F4 usart interrupt - necessary?

I'm struggling with adding usart interrupts to my code. My rotary encoder uses interrupts and the touch screen keypad is polled. I'm not transferring a huge amount of data, just records of about 20 characters at the most. Today instead of interrup...

Plans for more stm32wb chips and nucleoboards

Hello, I was wondering if there are plans to make another stm32wb series chip with an internal DAC and maybe some op-amps. Also, will they make nucleoboards for these chips?
