Question 1

QUESTION: Why aren't nested interrupts working on the R5F core on the AM2434/AM6442 when using VIM? This question is not about someone reviewing my code. It's about trying to understand the ARM R5F ...

Question 2

Within an XC16 assembly code portion, I want to use a C variable as a literal. Here's a portion of my code : C function : int x=4; int *TrisCSX = (int*) 0x2C8; x ...

Question 3

I am attempting to repair the following piece of electronic. The tactile switch is an interface for the on/off button that on the case of the device. I have tried soldering the tactile switch onto the ...

Question 4

In a PIC24FV32KA302 C code, I want to add inline assembly. For this, I use, for instance, __asm("BSET PORTB,8");. When compiling, I get the following ...

Question 5

In the following 14 layer PCB, there is a flip chip assembly for one of the chips, the chips is very fine pitch around 200 um: Considering that in flip-chip assembly, the heating process occurs from ...

Question 6

In a manufacturing line, we need to close a 30pin, top contact 0.5mm FPC connector, something like Amphenol F32Q-1A7H1-11030. We use pliers for that, insert the cable, close on one side, then close on ...

Question 7

I am planning writing an elaborate swarm-like (8-16 chips with no common bus to speak of) solution. Given that I plan on storing 3k of data (considering implementing compression) and need some clarity....

Question 8

I understand that when in assembly I input a command like XOR or SLL I have the opcode bits and the funct bits which tell the MIPS what to do, but I don't understand how it does so. When looking ...

Question 9

Unable to solve the above question. Getting error A40:invalid register when running this code on XRL instruction: ...

Question 10

Initial Problem I'm trying to make a push-button incremented counter on two 7-segment displays ranging from 0-10. Ultimately I want Timer0 to handle the 7seg multiplexing and another timer for ...

Question 11

Before explaining the problem I want to say as a disclaimer that I am a total beginner with baremetal coding in ARM, so the problem could be anywhere. I am following this guide to move my first steps. ...

Question 12

Currently, I'm working with Jetson Nano 2Gb, and I facing the problem about assembly when I debug with gdb, I receive ...

Question 13

I want to simulate **the Entry set mode ** function of and LCD based on HITACHI 44780 Controller. (Here is the datasheet.) The "Entry set mode" is given the following code of the 8 bits data ...

Question 14

Even though MC14500B is considered as 1-bit computing where it accepts 1-bit data to perform operation, the instruction set itself consisted with 4-bit instruction which leads having 16 total ...

Question 15

I am currently trying to indirectly address the SRAM of the ATMega328P by using the following code: ...
