Compiling code to run from external RAM

I am considering designs for a minimalist game system based on a PIC18F85J5. Part of my design is that games can be loaded from an SD card without reprogramming the chip or flashing the program memory. I chose that chip because it has an external…

PIC32 vs dsPIC vs ARM vs AVR, does the architecture matter when we are programming in C-language anyways?

We are currently using 32-bit PIC32 Microcontroller. It is working fine for our needs, but we are also exploring other microcontollers that can suite us better + we have other projects for which we are selecting MCU. For that purpose we have…

dsPIC chips running at a fraction of normal speed

I have two PCBs. One has a dsPIC30F6012a, the other a dsPIC30F6015. Both are being programmed from separate standalone HEX projects in MPLAB X, using a PICkit 3. Both firmwares have been applied to dozens of units prior to this point without…

Need some help understanding PIC memory map

Some background. I use MPLABx with a PicKit2 to program different types of pics. At the moment its the 16F887. I try to stick to the Hi-Tech PICC Lite tool chain but I'm growing increasingly unhappy with how some things are assembled. Operations…

L3G4200D random spikes

I've searched this forum a bit in regards to the L3G4200D gyroscope, and haven't seen this problem mentioned, but I have seen others talk about it on other forums. I am seeing a strange large value in my output when the gyroscope is stationary.…

Large array in C18 causes device reset

I am using the PIC18F13K22 and Microchip's C18 compiler in MPLABX. The PIC kept resetting, when it was about to jump into the interrupt service routine (ISR). I was able to trace the problem down to the declaration of an array: UINT16 rom periods[]…

Interrupt Service Routine in C - function at specific address

I need to add an Interrupt Service Routine (ISR) to existing code in C for a PIC18F4620 and a PIC18F46K22. As you can see in section 9 (of both datasheets), these devices have multiple interrupt vectors: 0x0008 for high priority interrupts, 0x0018…

PIC measuring PWM pulse length

I'm just getting started with PIC processors, driven mainly by a shortage of the simpler PICAXE from my local retailer. My question is, how do I read the length of a PWM pulse on a certain input pin (analogous to the PULSIN command on PICAXEs). I'm…

Interfacing PIC18F4550 with I²C EEPROM (24AA1025)

I am working on a university project in which I need to interface a PIC18F4550 with an I²C EEPROM. I read many codes and saw many projects on this topic. And I wrote a sample code from MPLAB C18 (and I tried many codes also), but no one worked with…

How do I detect / retrieve the silicon revision of a dsPIC?

Before starting on my project, I need to familiarize myself with any possible silicon errors in my dspic. I saw this for PIC micros, but it doesn't apply to the dsPIC33F that I'm using. I found a post somewhere (that I can no longer find for some…

Can't read written data out of 24AA1025

I've got a PIC18F with MSSP that I'm interfacing with a 24AA1025. I'm using MPLAB 8 and the functions from C18 to make my life easier. The only problem is that I've (supposedly) written a byte to the 24AA1025, but when I read it back, I get 0xFF…

PIC18F4520 ADC Conversion in MC18

I have a dilemma. I need to read ADC values from PIC18F4520. My configuration, and code, is as follows: #define OSC INTIO67 int adc_result = 0; void main(void) { OSSCON = 0x70; //Set it as 8Mhz. OSCTUNEbits.PLLEN = 1; //Enable PLL 4x…
