Hello,

As you told me , i used another MCU to generate a 32Mhz clock pulse and gave it to X1. I connected X2 to ground. But still no luck. I get back only the data that i have written into the HT1380.

What else can be wrong. ???


Use a 32kHz signal to X1.
X2 must be not connected at all.

David.
