Posted on April 18, 2018 at 17:00Does anyone has been able to use DFSDM to filter data from the internal ADC?I have ADC triggered by a timer in order to acquire data equidistant in time.It works fine but I need to filter them better than using its o...
Posted on April 18, 2018 at 15:01Recently, I've encountered problems with 'HAL_UART_Receive_IT()'. So I go here for solutions. I see several suggestions to put another 'HAL_UART_Receive_IT()' in 'HAL_UART_RxCpltCallback()', but they didn't give whi...
Posted on April 18, 2018 at 06:43HiAfter looong work with Microchip's PICs we are moving our desing on the fly to STM32L4 series MCU because it has hardware SDIO core. After some tests I see 55Mbps on STM32L476-EVAL with microSD Class 10 and 32KB bu...
Posted on December 22, 2017 at 15:58I have a problem understanding the choice of BankNumber value:1- how to choose the BankNumber value and the relation with the FilterNumber register2- what is the register that must support the value of BankNumberT...
Posted on April 15, 2018 at 10:06Hi to alldatasheet 13587 Rev 17 5.3.1 table 9 says: Vdda must be same potential as Vdd with a maximum diff of 300mV (footnote).5.3.18 table 46 says: Vdda must be between 2.4 - 3.6 and not mentioning anything about Vd...

Posted on April 18, 2018 at 12:00Hi to all,I'm working with an SPWF04 wifi module linked on NUCLEO F411RE board, using MQTT protocol; all works perfectly but I'm wondering if there is a maximum length (in byte) for a MQTT published message. So, when...
Posted on April 17, 2018 at 13:18Hello. At page 212 in the manual RM0008 for the STM32F103 device, some part of the internal/software event is explained. Under the EXTI_PR it states, this bit is cleared by writing a '1'into the bit. But just above ...
Posted on April 18, 2018 at 11:18 Hello everyone, I'm trying to connect M24SR to the microprocessor STM32fF407. Previously used the STM32fF107VC processor, and a slightly corrected demo version of the software for the M24SR Discovery, everything...
Posted on April 18, 2018 at 09:59Hi, I'm working on a project and the code works very well (stable, no crash...). But recently I decided to add EEPROM emulation and therefore started to add some code and test. I realized the emulation wasn't working...
