We are using STM32L151RBT6A device. As per the specification we should be able to have access to 80bytes of RTC backup memory , but we are able to access only 20bytes of Backup registers memory. As per RTC backup registers description , for value li...
I have the problem that I don't get the NSS configured correctly on my SPI transmission. I should get according to reference Manuel a NSS signal that switches just before the first bit and just after the last bit. I send several different data one af...
We received a batch of MCUs, STM32L072CBT6, LQFP48, on suffix of marking section has marked revision “1�?, marking on MCU are also marked with “1�?.As per STM Errata sheet, there are different markings such as 1, P, Q, Z.But I can only find related i...
I am using the stm32h745ziq-nucleo board . I am generating the pulse in the cm7 and I am trying ton capture the falling edge of the pulse. I am getting the falling edge capture for every falling pulse But I want to capture only the 8th falling edge o...
I'm developing application on stm32H7 and a need to execute small function from RAM. I add RamFunc derective, and describe in linker *(.RamFunc) in .data section. As a result, i certainly see, that function code moved to RAM address space. I compare ...
Posted on December 07, 2016 at 21:47 There is a problem with IDE debuggers for STMF7, and as I understand, all ARM M7 core based processors. With other CORTEX controllers, when a debbuger pauses or hits a breakpoint, the debugger stops interrupt pr...
Hi,I like to implement a I2C slave on a STM32G081 with using stm32cubeide.Basically, it is working.Sometimes, the system communication stuck while a transaction on the STM32 I2C slave is active.How can I implement a clock stretch timeout on slave sid...
Hi,I´m using an stm32f401 and observing suspicious behaviour on the I2C slave.My issue is that I get transmit completed callback after master has read 1 byte, but I have called HAL_I2C_Slave_Seq_Transmit_IT to send 2 bytes.I´m trying to send 2 bytes ...
See what new users are writing:What are the differences in I2C configuration between these two processors?How do I set the embedded ST-LINK on the discovery board to DFU mode?is there a similar way to use USB transfer without blocking the main loop?h...
May I know the production schedule of STM32F469NIH6?It is impossible to develop using STM32F469NIH6 due to an unbelievable price increase in the market. If you let me know the production schedule, it will help me adjust the schedule.
