Hello, I know this might not be the best place to ask, but we are kind of desperate ! I have a system with a LPC2148 ARM7 and a LPC915 (operating as a I2C slave to the '2148) and I need to get the LPC915 to work... I have other devices on my I2C bus, and the 2148 talks ok with them. The problem is to make the I2C slave code work on the LPC915 (I'm currently (trying to) using the skeleton from esacademy. So anyone have some working examples (or willing to do some contract work ?) PS: Sorry if this is "mis-placed" on the forum.... Regards, Carsten
i have LPB93x slaves working with no problem using ESacademy code as a base. "a base" does not refer to the esacademy code not working, just not 'as I want it to look'. Erik
addition to the above: I have, when using the CodeArchitect code the first time used it 'as is' then gradually, while ensuring functionality at regular intervals, changing it to what I actually needed (switches inside the ISR and such). "Carsten Groen", you Danish? Erik
Hi Erik, "ja jeg er :o)" OK, I have been "fooling" around with the I2C isr routine in the LPC915, and it seems like when I try to do a simple "write 1 byte" from the 2148, I get a status 0x00 in the ISR..... Erik, do you have a private email address ? Regards, Carsten
Hmm, it might also be the code on 2148 that is the cause of the error, I use the code to talk with a DS2745 (fuelgauge) and a PCA9535 though without problems.... Carsten
