Device not send the join uplink when change the keys from OTAA to ABP

Hi,​​​I have used Stm8 controller and I have change the keys from OTAA to ABP. In OTAA mode I have get the joining uplink(first uplink) but i didn't get the joining uplink in ABP.​ When I reset the device after get the second uplink in the network se...

I'm writing an STM8 assembler using your PM0044 document, but it has errors. For example, BTJF and BTJT are both listed as having an opcode of $72 $0x (the x is the bit mask). Most likely, one of those opcodes is supposed to be $92.

Most likely, the programmer who wrote your assemble used a text document provided by the engineers for his info on the STM8 instruction set. Later on, a technical writer converted that text document into a snazzy PDF for outsiders such as myself. Err...

What exactly happens if the class b complementary check is interrupted?

To protect variables in a class b application a redundant complementary variable is stored in a separate memory location. The idea is to check if the exclusive or of those 2 variables is 0xFF before using them. My question is what exactly happens if ...

Guys could you please suggest me some microcontrollers or discovery kits which support IOT Gateway

Problem useing SPI together with UART as SPI

As soon as I add USART initialization, SPI starts sending data using LSB and receiving with MSB(as it was intended) bit order.SPI init code:/* SPI configuration */ SPI_DeInit(); /* Initialize SPI in Slave mode */ // SPI_Init(SPI_FIRSTBIT_LSB, S...
