Description
I tried to design a custom btnm, it’s similar to our daily keyboard like “CapsLK” function and so on, but when I changed the map of btnm, some of expected sequence caused my hardware reset,.See the code below, “Up” “Down” btn is OK to change, but “Num” and “FU” btn caused my hardware reset.
What MCU/Processor/Board and compiler are you using?
RDA borad.
What do you want to achieve?
Design a keyboard as we use daily on mobile phone.
What have you tried so far?
I tried to replace the btnm map with the previously one and that two btn works, so I guess this matter with the content of btnm map, but I don’t know why.
