I am trying to control the amplitude of a triangle wave, while the frequency of the waveform should always be 1kHz. Is this possible to do?The reference manual says that I can control the amplitude of the signal using the register DAC-> DHRx. Further...
I'm using the STM32F303xx MCU in an application with a 24.576MHz crystal. The MCU is powered from 3.3v. I am currently clocking the processor at 3x 24.576MHZ, or just slightly under 74MHz. I realize this is above the rated maximum processor clock ...
Hi. I bought stm32f469i and Nucleo-h745 boards. H745 connects to STLink no problem. But the F469 discovery board doesn’t connect. I tried installing reinstalling drivers, connecting to other computer nothing worked. I couldn’t find another cable that...
I have the code working fine with the 1byte, 2bytes and 4bytes programming, reading and writing. But when I use the 8Bytes (double - word), It is always trapped in a hard fault handler. Any help?
I use the MCO pin to test my clock configuration on a STM32F072RBT6 board. While I'm debugging with a ST-Link/V2 adapter the MCO output shows 24 MHz instead of the expected 48 MHz.Using the exact same software (no changes in clock configuration) and ...
Hi,Im using the STM32F746NG Discovery Kit MCU. Im getting following error when trying to make a HTTPS connection:mbed_tls ctr_drbg entropy source failed.Although I enabled the RNG and CRYP Module I put following macros into my mbed config.h:#define M...
We are developing a product and are stuck at Firmware over the air updates. It seems like we will need a system that meets the following requirements:From a firmware perspective, the platform should support delta updates so the entire firmware packag...
Hi,We are trying to interface STM32F76 custom board to DS3231MZ+ RTC chip ,we are able to set and retrieve time using I2C and it is incrementing properly as long as board is powered up. But Time and date are reset to 0:0 and year 2000 after board...
We are using STM32F769 NI with DS3231 MZ+ rtc , the rtc is not holding time after a power reset .The reset pin in the DS3231 circuit is floating , althouigh reset pin has an internal pull up of 50k , can i leave the reset pin floating or should i con...
