Post by thread:16C84 data eeprom and picstart16 help needed

Please, some expert advice needed. A friend of mine asked me to help him to program 2 16c84 (I'm only using 5x types my self yet). The problem is that he need some data in the data eeprom part that i don't understand how to program from my picstart16b. I have seen in an application note that it is possible at least but could it be done from my picstart16b? While trying to program one of these i filled the buffer with zero's and programmed it without complaints (except id i think) but when programming it with real data there was errors already at pos 0x13. Could these little bastards fail like this? regards /Sten --- Sten Dahlgren CelsiusTech Systems !

I'm having just the same problem as you. I have the picstart16b1 and I need software which is compatible with the hardware from picstart16b1 and this software must be able to write to the eeprom memory on the pic16c84 chip. If you get the solution to this problem, please mail me. Or if you get the software that works with the picstart16b1... or any info at all... please mail me. PS! I got the program Promate 3000 which has support for the eeprom programming, but I don't know for sure if it's compatible with the picstart16b1 hardware device. But another 'but' is that this program has an option called 'Download Firmware'..... So there is a possibility that this could make the program compatible with the hardware. I have sent email to Microchip about this, but I haven't recived any answer from them........ Hope we could share some information on this.......

If you get the solution to I also has the picstart16b1 and I asked Memec Scandinavia (the distributor in Sweden) about this six months ago. The only answer was that it was not possible ... One solution however is to create a program that takes input via RS232 and writes all eeprom locations in the 84. Of course you need another "programmer" to accomplish this. -- Conny

Erik Herman's RS-232 Programmer combined with Anniti Lucas's PIP-02 program will permit writing to the EEPROM area. I often use it to quickly change the sequence of a light chaser- and also for many other purposes. Sorry, I forgot Anitti's link, but it is listed on my web page below.
