These chips had transparent glass windows on their top that allowed the memory to be erased by ultra-violet light.

You'll have to sort the problem out with the supplier. Write a test program that simply reads the EEPROM, outputs the byte read on a port and waits long enough for you to see it on a set of LEDs then Top MikeB 9x Developer Posts: 13028 Joined: Tue Dec 27, 2011 1:24 pm Country: - Location: Poole, Dorset Hasthanked: 87 times Beenthanked: 2247 times Re: Can't read EEPROM file in 9xr I'm not quite sure what to make of that page(?) What would I have to do to install eePe?

It is possible with EEPROM that the memory in the IC became erased. try the code on a SILabs devboard if you do not have an ICE good tools are half the job, thus buy two sets :) Erik Read-Only Authorsayonee sayonee Posted30-Nov-2011 15:59

Problem solved, (after much messing around with eePe), by biting the bullet and Flashing the 9xr with:OpenTX r2940 (variant 215 32768) and;Companion 9x-mac v1.52 (rev2396) from the Companion9x-mac v1.52 update dmg.Kept http://haywirerobotics.com/cannot-read/openvpn-crl-cannot-read.html delay(5000) the value of the eeprom will be displayed at serial monitor even if i do not use the while(!Serial) command.

I was originally using a 9x radio and was configuring it with eePe. Why is RN2903 dropping packets - only around 1 in 8 packets is getting through LoRaWAN looks great, but I don't want to pay a subscription.

It seems the problem is not limited to the r405 version .. To reconfirm the working of my Microcontroller Kit,I am using a similar kind of program( found on this forum ) for interfacing the EEPROM using I2C and this program works!!.

This string should start with 'w', 'r' or 'e', depending on what action I want to perform. You can change this preference below. This site does have a facility for posting code here. SDA ){} ...just to check the timimg on the simulator of KEIL V4 ...everything seems OKAY but again to REPEAT EEPROM_write() is doing the same as EEPROM_read() and checking of ACK

So no doubt both the EEPROM_read() and EEPROM_write functions call the same I2C related function its only the EEPROM_read() which is succeeding THIS IS STRANGE AS ITS TANTAMOUNT TO SAYING THE I am trying to get max help from all ..but still nothing :( ..heres one post ..
