when i probed the pin of the respected port and view them on the MSO i found the delay between them.Port B was initialize first and port E later even though initialize the Port E first and Port B later. i don't want this delay between the port E and ...
I'm using ST Visual develop and Cosmic to program a STM8S003K3 and I'm thought it would be nice to use the STM8 Standard Library (downloaded from ST.COM). Within a very short time I got errors telling me that I tried to put more code in the MCU than ...
When the input to the ADC (in the STM8L151G6) is floating, it reads approximately a mid level value. For example, if the ADC's reference voltage is 3 volts it reads around 1.7 volts. Why does this happen? We can't find a register setting that causes...
I used ST Visual Programmer to check if soldering's been completed well.I didn't open any files but just clicked the programming tab (the red arrow one) but the message that it cannot communicate with the device popped up. It still didn't work when I...
We are currently experiencing a problem with the STM8AL3166, The I2C is set up as slave and when reading data from the STM8, first a sub-address is writtten to the STM8 whereafter a repeated start is issued. The I2C must be working in polling mode)....
I've noticed that in the STM8 standard peripheral libraries, in the UART3_Init function there is an assertion checking the baud setting:assert_param(IS_UART3_BAUDRATE_OK(BaudRate)), which limits the baudrate to 625000.BUT according to the datasheet t...
I'm trying to use TIM1 to output a PWM signal on stm8s103f3 using the standard library (patched) with sdcc compiler.The output goes high, but there's no signal.#include "stm8s.h" #include "stm8s_it.h" /* SDCC patch: required by SDCC for interrupts...
#include "stm8s.h" //My delay for testing. Calibrated for milli seconds. void delay2(uint16_t ms) { volatile uint16_t a = 100; while(ms--) { a = 1800; while(a--); } } void main(void) { //CLK_DeInit(); CLK_HSIPrescalerConfig(CLK_PRESC...
I've been working with STM8S chips for about 2-3 months now, and would like my doubts clarified:What is the state of the RAM in the chip after a software/watchdog reset(Not BOR or POR, obviously). I have assumed the RAM is not disturbed by the Reset,...
Please go through the code and help me out in the configuration.void i2c_init(void) { I2C1_FREQR = 0x20;// 16mHz I2C1_CCRL = 0x50; // 160 I2C1_OARH = 0x40; // 7-bit addressing and add-mode configuration I2C1_CR1 = 0x01; // enable peripheral}void ...
