PSoC 1 UART + DAC + ADC: RX Data lost //Float to String C ftoa() Code with decimal place definition + negative numbers

Attachments are accessible only for community members.

Hello,

im receive some data (RX) via UART :

1. convert it (atoi()) into a Integer,

2. conver it (itoa()) into a String and sent it (TX) via UART.

Meanwhile, reading 2 voltages (dualadc) and output (dac8) one voltage.

Problem -> If i comment-out all ADC and DAC Code, the UART Communication works fine. But with all User-Moduls + miniCode the UART Communication is faulty (irregular).

:: What can i do?

Settings:

Global Settings = 24Mhz, (Vdd/2)+/-(Vdd/2), SC On/Ref High

UART = 9600, Sync to SysClk,

DUALADC = 8 Bit, CalcTime 45, DUALADC_HIGHPOWER, PGA_1_HIGHPOWER, PGA_2_HIGHPOWER,

DAC = DAC8_HIGHPOWER

Thanks for your reply.
