Please can someone help me with the c/c++ code for this project am doing, the circuit is the picture of my project,it measures heartbeat using LDR an an LED light source, the analog signal is the amplified by the Opamp LM358 which is the fed to pin P3.4 of the microcontroller which outputs it to the serialbuffer SBUF,please can u help me with a C/ C++ code for this project.
this is where i need to convert hex values retrived from counters to ascii decimal values which is sent to the serial buffer of 8952 microcontroller,Please can anyone help me with the C code to masure the Data at P2 and also count the Number of pulses it receives from the Opamp LM358
as per the circuit the heartbeat sensor output is given to T1 (timer 1) input pin. so you can configure T1 as counter and read pulses in 1 sec so you can get value of heartbeat per second. check frequency counter project for reference.
And for temperature sensor, you need to read ADC value then convert it to corresponding temperature value. www.rickeyworld.info If you feel satisfied with the user's forum reply please click on the thank button.
pls how can i set the counter to read pulses @ exactly 1sec and am using timer 1 as timer for the serial port baudrate and timer/counter0 for counting of the pulses.(P3.4= T0)
PLEASE how can i set counter 0 to resd the pulses @ exactly 1 sec in C.
make timer to trigger at every 50ms so 50ms triggered 20 times means 1 sec delay.
use counter to count 50ms triggers. check your circuit carefully, timer 1 is used for heartbeat sensor. www.rickeyworld.info If you feel satisfied with the user's forum reply please click on the thank button.
yes i made a mistake on the circuit,pls can you give me the exact values i will load on my counters (TH0/TLO) to achieve this, thanks for your anticipated favourable response.
