Variable Symbols in File Register

Hi Group, Is there any way get MPLAB asssembler to show the cblock symbol names from a list of variables created by cblock? With a large cblock of 30-40 variable symbol names it gets to be a real pain to find the right address when looking in the file register while debugging. Also, with byte size variables, MPLAB does not include or allow me to drag and drop any of the cblock variables ...

Dear All, ? Need Help! ? I?want to know whether the chips designated "LF" (low voltages devices, Example :PIC18LF2580 ) can be used as normal "F" designated chips( Example: PIC18F2580). I know the vice-versa is not true.?Whether all the ports,I2C,SPI,SERIAL n so on?etc ?of "LF" chips? function as standard "F" chip at +5V. I mean are there any restrictions or limitations. Can i replace PIC18F...


PWM to 0-10V Output

I have recently come across a circuit diagram: http://f1.grp.yahoofs.com/v1/ULBpSg7H1FfAWrKBp02HDaRkyq4iFpOjfpH78Kql4Dxq0CgSrNLnPzPzZIhq_C7J8z1 8rM7VyWwp3bC8n2uBiJDZsrfy/PWM.jpg Now the purpose of this circuit, is to convert a 5V PWM Signal to a 0-10V Output. The details of the PWM are unknown. So it could be a normal type of PWM, with the mark to space ratio changing, but seen as it is a

I'm looking for suggestions on how to learn surface mount soldering, as I only know how to solder through-hole. What training products can I buy to learn? What surface mount project kits would give me good practice? What soldering iron tips should I buy? I have a WES51 soldering station and would prefer to stick with that. ------------------------------------

I'm part of the Data Acquisition subgroup of Project Phoenix, a group working on an open source blood pressure monitor. I'm trying to figure out what surface-mount microcontrollers we could use. I need to figure out what our options are before I decide what programmer to get. Page 2 in the following PPT presentation shows what kind of input the microcontroller needs to process: http://www....

Dear Friends , ? I am trying to make? 4 axis stepper motor control , but i am stuck in the software part logic. ? i will use L297 and L298 as stepper controller and driver. ? ? For L297 i must give?step input and direction. Since my control is of 4 stepper motor, so how can i generate 4?INDEPENDENT?step signals?from PIC (?PIC18F4580 i have , but if it is possible?from other PIC ,?please...

Hello again, I think I've exhausted myself over this one. SPI is supposed to be REALLY simple, right? But, I can not get my SPI slave (PIC24) to do even recognize that SPI is happening at all. Here is the rest of the story: My project has two MCU's in it. A dsPIC30F3012 that reads the sensors and performs all the fun DSP stuff. It is the SPI Master and spits out data for the PIC24HJ64GP5...


Timing a 20KHz signal coming into a PIC 16F88

Started by silverfoxgmail in Piclist8 years ago 5 replies

I have the need to measure the duration of short bursts of a square or sine wave signal coming into a PIC 16F88 at a constant frequency of 20KHz....

I have the need to measure the duration of short bursts of a square or sine wave signal coming into a PIC 16F88 at a constant frequency of 20KHz. The bursts last between one and 150 milliseconds and I need the time measurement to be accurate to about a half millisecond. I was thinking of using an interrupt-on-change on the input pin and saving the time of the first interrupt and subtract it from...

if you look in the files section under sr_gamer you will find the schematic and the program for a clock I'm building. The display is VERY dim. I'd like the display to be very bright. These elements are very bright when supplied with 5v, which should be what is coming off of the PIC, so I'm either suffering from low duty cycle or having trouble sourcing enough current. I tried some 1k pull ...
