Hello, Can I say that "IDLE" is equivalent to "RTO with 8-10 bits (depending on framing)"?Or are there some other subtle differences? My goal is to transfer received data with DMA and start interpretation of the data when nothing is received on the l...
Hi i am using STM32U585 to interface with fuel gauge using i2c. I want to know the internal pull down of ST MCU and if needed what should be the external pull-up resistance value.
Hi I m using F072 Nucleo bd, and compiler report the following errors but there was no syntax error from the code, can anyone advise?22:08:09 **** Incremental Build of configuration Debug for project F072_GPS_ NEO-6M_i2c_LCD_16x2 ****make -j8 allarm-...
Hi,I'm working on a STM32H755BIT6 with a custom PCB layout, which uses direct SMPS supply hardware configuration.I'm migrating an existing Keil project which was created with STM32CubeMx 6.7.0 to STM32CubeMx 6.11.1 and I discovered that the option PW...
I'm using an STM32L051K8. I'm writing words to EEPROM. It takes a lot of time to do that. I read in the datasheet that it is possible to do a half-page write that will take the same amount of time as a single write. How do I write a half page? Do I u...
Hello everyone,I have to work on an already existing project using the STM32F769I_DISCO which works properly. My task is to write logs in a file on a SD card. I followed the excellent tutorial by Nicolas Fillon for STMicroelectronics about the matter...
OTP portion of FLASH is a valuable asset in some STM32 families and represents a convenient place to store things like security keys. For this, it is desirable - and, as it's part of FLASH, also quite logically expected - that setting read-out protec...
I will be using 16 channels of STM32 ADC and I would like to protect them against overvoltage and ESD (those will be used as device inputs and unwanted situations can happen), my initial thought was to use a Zenner diode array and current limiting re...
Greetings!I generate periodically a 10MHz PWM signal of 8 pulses. The PWM signal has high polarity so the first edge is falling. I need to generate an interrupt/event on the rising edge that'll signal DMA to move data from a GPIO IDR to a data buffer...
Hello,I am working on a STM32L073V8T6. I want to use the 1/3 bias functionnality to manage a screen.I have configured the contrast control to 3.26V, the Mode to 1/4 Duty Cycle and the Bias Selector to 1/3 Bias. But if I write something to COM0 and...
