That question started bothering me when I was struggling with TLE493D that started interrupting using the i2c clock line.It looked like the i2c in the F429 was gone bananas and keeping the i2c stuck (busy).I was thinking of feeding the i2c the clock ...
Currently I try use STM32F103RCT to implement I2C slave to communicate with master. When master sent address with write bit , there is no any problem and all data can be transmitted to slave through I2C, but when master try to read, it seems big prob...
I'm using a STM32F105RBT6 in LQFP64 package in a project. The datasheet suggests using a crystal or resonator. I want to use a 4-pin oscillator that has a single output pin. Is this possible and if so where do I connect it?Thanks.
Hello,I would like to signal a possible error on the reference manual of the STM32L496 (RM0351 Rev 6)At pag 348, section 11.4.5, Table 45 the first line (source port 8bit, destination port 8bit) indicates that the Number of data items to transfer is ...
HelloWe ran the ADC DMA on the HAL example source. However, I tried to write the source in CUBEMX, When executed, the DMA interrupt is executed once and is not executed again.Please let me know if I missed anything
Hi,I have an application of which uses the STM32F469NI with two MX25L12833F QSPI flash in dual flash mode and are encountering an issue when using HAL_QSPI_AutoPolling().CLK is configured at 1MHz (to allow for logic analyser), both devices share the ...
I am using the STM32H743II package (with Vref+ and Vref-). Those two pins are not connected in this design (they're left floating). I'd like to measure the temperature of the chip, and am having trouble using the internal voltage reference as the ref...
Hi community,I'm currently trying to set/reset the BFB2 bit from application program, under MBed, with a STM32L476RG.Though setting/reseting BFB2 can be done properly thru ST-LINK, I did not manage in modifying the option bytes, using the HAL/LL driv...
Hello there,We are using your STM32F030K6T6TR MCUs extensively in our Fotokite systems. They communicate via I2C. We have different MCUs on different, isolated grounds and are therefore currently using the Si8602AC-B-IS I2C isolator. This device does...
I use stm32l496. before entering the low power run mode I set the output but when micro enter lprun the output is reset.I want to know what the status of the outputs is at low power mode?andcan the outputs be changed or read?thank's.
